Understanding Plaster Ceiling Cracks

Plaster ceiling cracks range from minor hairline fissures to deep, structural splits. These cracks occur when the plaster material loses its bond with the lath or when the ceiling structure shifts.

Common Causes of Plaster Ceiling Cracks

Several factors can cause plaster ceiling cracks. Foundation settling is a primary culprit, especially in older homes. Moisture damage from leaks or high humidity can weaken plaster. Poor installation techniques, such as inadequate lath attachment, also lead to cracking. Additionally, temperature fluctuations cause materials to expand and contract, stressing the plaster.
